They recently introduced "straight python" components i believe, so you can just write in that. Additionally there are multiple apis you can use to interface other than the front end at https://home-assistant.io/developers/api/ https://home-assistant.io/developers/api/ Also the HA front end just calls those backend apis, so if you "emulated" those you could use it as a drop in for some other backend (in theory)
